Application led September 3, 1908. Serial No. 451,466.

To all whom 'it may concern:

Be it known that l", RUDOLPH Ennnrmnn, a citizen of Switzerland, residing at Stockton, in the county oi San Joaquin, State of California, have invented certain new and useful Improvements in Leveling instruments; and l do declare the following to be a full, clear, and exact description oi' the same, such as will enable others skilled in the art t0 which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in leveling instruments used for leveling land for irrigation, planting or other purposes, the object of the invention being to produce an instrument which any person can handle without the necessity of the use of iine and delicate surveying or leveling instruments such as are now used. Also to produce an instrument which is simple and inexpensive of construction and yet especially eilective and adaptable for the purpose for which it is designed. This object I accomplish by means of a flexible hose of suiiicient size to permit an easy flow of liquid, preferably water, from end to end thereof, said hose being connected with a suitable handle member at each end, such handle members having graduated tubes disposed therein transversely with respect to such hose, said hose and parts being strengthened by means of an interior Wire member, the scheme of the invention being to fill such hose with water and then when the ends of said hose are placed at spaced points the water in the tubes will rise to the same level thereby indicating whether the land at such two points is level or not.

Such other and further construction and relative arrangement of parts are also employed as will appear more fully by a perusal of the following speciiication and claims.

In the drawings similar characters oi reierence indicate corresponding parts in the several views.

Figure l is a side elevation of device. Fig. 2 is a vertical section oi the same. Fig. 8 is a section talren on aline 8-3 oi Fig. l. 1Eig. 4 is an enlarged tragmentary view ci a tube and tube holder. Fig. 5 is an enlarged fragmentary view of a the complete hose and connection showing a strengthening wire therein.

Referring now more particularly to the characters of reference on the drawings l designates a flexible hose oi desired size and length the same being suitably spaced into feet as at 2.

3 are handles at each end of the hose l and having connecting tips el over which the hose l iits, there being an orifice 5 in said tip 4 and handle 3 corresponding with the hole oi the hose l and turning at right angles with said handle 3. A wire 6 extends through the hose l to keep it from stretching and is hooked into the tips d, Screwed into the handles 3 are hollow tube holders 7 coinciding with the holes 5 and having vertical side slots Shaving oliset shoulders 9 at their lower ends, said tube holders having bottom shoulders 10 against w ich rest glass tubes l 1 opening into the holes 5 and iixed in position by suitable adhesive material i2, such as white lead, iilling around the shoulders 9 and 10. The tubes 1l having removable top corxs 13. At the side ol the slots 8 on the holders 9 are graduations le to indicate the height to which the water rises in the tubes l1.

In practice oneoi the corls 13 is removed and the hose l iilled with liquid. Then the tubes at its ends are carried to the different points oi the land to be leveled and such tubes are raised or lowered until the water stands at the same level in each as indicated by the graduations l and then the distance between such tube and the ground. designates the amount oi difference in the level oi the ground. Should the tubes l1 become broken they can be easily removed from the holders '7, and replaced by new ones. The Wire G prevents the hose l from stretching and thus preventing any accurate measurement by the graduations 2.

From the foregoing description it will be readily seen that l have produced a leveling instrument which substantially fulfils the object of the invention as set forth herein.

lihile this specincation sets forth in detail the present and preferred construction oi the device still in practice such deviations from such detail may be resorted to as do not iorm a departure from the spirit oi the invention.

Having thus described my invention What extending through said tube and engaging I claim as new and useful and desire to 1 said handle members, as set forth. secure by Letters Patent is In testimony whereof I affix my signature A leveling instrument comprising handle in presence of two Witnesses. 5 members transparent tubes disposed therein7 RUDOLPH EBERHARD.
